Effective Data Transmission Efficiency in RGB-LED Based Modified MPPM System

In this paper, the average retention time, average recovery time, symbol error rate, and effective data transmission efficiency taking account of the synchronization performance and the symbol error rate in a synchronization method using two binary pulse position modulation (BPPM) signals of adjacent modified multipulse pulse position modulations (modified MPPMs) have been evaluated. It is found that there is an optimum value for the number of pulses generated in the modified MPPM frame in terms of synchronization performance, the symbol error rate, and the effective data transmission efficiency characteristics.
